Technical overview: This JAZRIDER kit supplies precision metal shielded ball bearings sized for typical M05 and M06 bearing locations. The set configuration is 12 of 5x11x4mm and 6 of 5x8x2.5mm to match stock bearing points. Fit bearings into clean housings using a driver that contacts the outer race to avoid inner race loading. Regular light lubrication preserves service life and minimizes rolling resistance for consistent drivetrain performance.
